What Is a Swap Body?
A swap body is a detachable freight load unit with no axles, no wheels, and no coupling mechanism — held independently on four folding metal legs when removed from a truck chassis, designed for transfer between road vehicles, rail wagons, and short-sea vessels without unloading the cargo inside.
The body swaps between carriers; the goods stay sealed throughout.
How Does a Swap Body Work?
A swap body attaches to a truck chassis when the driver reverses underneath, the air suspension lifts to take the body's weight off the legs, and locking cones on the chassis engage the body's base rail.
A full exchange takes 10 to 15 minutes for an experienced driver with no crane or handling equipment involved — the folding leg system handles the entire road-to-road operation on any level surface.
What Are the Standard Dimensions of a Swap Body?
Swap bodies run in three standard length classes — 7.15m to 7.82m for Type C, 12.192m for Type B, and above 13.6m for Type A — governed by European standard EN 284.
Type C is the most widely used class across European road and intermodal freight. Standard lengths are 7.15 metres, 7.45 metres, and 7.82 metres.
Type B bodies measure 12.192 metres — the length of a standard ISO rail wagon — which places them directly on European rail infrastructure without dimensional adjustment at loading points.
Type A bodies exceed 13.6 metres and are used on European Modular System road-rail combinations.
What Body Types Are Available on a Swap Body?
Swap bodies run in five configurations — box, curtainsided, refrigerated, tank, and specialist — each built for a different cargo type and loading method.
Box body swap bodies suit palletised consumer goods, retail stock, pharmaceutical packaging, and electronics.
Curtainsided swap bodies allow forklift loading from either flank. Refrigerated swap bodies maintain temperature-controlled cargo. Tank swap bodies transport liquids, gases, and bulk materials.
What Is the Difference Between a Swap Body and a Semi-Trailer?
The defining difference is running gear: a semi-trailer has its own rear axles and a kingpin coupling, while a swap body has no axles, no kingpin, and no running gear.
A swap body completes the rail leg of an intermodal movement without any road vehicle, with the driver and tractor returning to road operations immediately after terminal drop-off.
What Is the Difference Between a Swap Body and an ISO Container?
The primary structural difference is stackability. ISO containers have reinforced top corner castings allowing stacking 8 to 10 units high. Standard Type C swap bodies cannot be stacked.
An ISO container follows ISO 668 standard, while swap bodies operate within European road-rail infrastructure under EN 284 and UIC 592-4.
What Cargo Is a Swap Body Used for in European Freight?
Palletised consumer goods, refrigerated food products, pharmaceutical cargo, automotive components, and high-volume parcel consignments are the primary cargo categories moving in swap bodies.
Retail, FMCG, food, automotive, and e-commerce operators use swap bodies for sealed high-volume transport across European intermodal and road freight lanes.
What Are the EU Regulations Governing Swap Body Transport?
European standard EN 284 defines the dimensions and general structural requirements for swap bodies in combined transport.
EN 283 specifies floor strength, EN 12642 Code XL sets cargo securing requirements, and UIC 592-4 governs how swap bodies are positioned and secured on European rail wagons.
How Does Go Trans Arrange Freight Using Swap Body Capacity?
Go Trans arranges road freight and intermodal freight across Europe through its carrier network, matching consignment volume, body type, and delivery address to the right carrier and service on each lane.
Swap body capacity runs on European road-rail corridors where rail trunk haul combines with road collection and final delivery.
